DC MOTOR (BRUSHED):
DC motor + Encoder Incremental
With this coupling set only the following parameter:
•
Resolution:
insert the value of encoder pulses/rev.
All other parameters are not to be set.
DC motor + Hall sensor
With this coupling set the following parameters:
•
Min. RPM:
minimum speed allowed in RPM.
•
Resolution:
the value is calculated with the following formula:
Resolution = hall cell number * 2
All other parameters are not to be set.
DC motor + Tachogenerator
With this coupling set the following parameters:
•
Offset:
in the oscilloscope set the "BEMF" option; then change the "
Offset
" parameter until
BEMF=0.
•
Tacho Voltage:
tachogenerator voltage [V].
•
Rpm.mot at Tacho Voltage
: turns referenced to the tachogenerator voltage [1000 rpm].
All other parameters are not to be set.
Tacho Voltage
is referred to the encoder voltage and not to the motor voltage.
In this configuration
Tacho Voltage
max is 40V.
DC motor + R.Armature
With this coupling set the following parameters:
•
Armature Resistance(Ohm*100):
armature resistance;
•
Motor Voltage:
motor voltage [V];
•
Rpm.mot at Motor Voltage
: motor turns correspondent to Motor Voltage [rpm];
All other parameters are not to be set.
"Motor Voltage"
and "
Rpm.mot at Motor Voltage
"parameters do not fix the motor voltage and
speed limits, but they defines the voltage/turn characteristic of the dc motor. Setting these param-
eters, it is possible to correct the slope of this characteristic.
The speed limit is the Speed Limit parameter.
